摘要
某矿采空区的存在,可能诱发冲击地压灾害。为了评价其稳定性,应用三维ANSYS程序模拟了采空区的形成过程,并应用先进的矿柱强度理论校核了ANSYS分析结果。结果表明:该采空区不会发生冲击地压灾害,但可能发生局部冒顶。
The existing Mined - out area may induce impact ground pressure hazard in some mine. For evaluating the stability of the mined - out area, the forming process of the minedout area was simulation with 3d - ANSYS software, and the analyzed results were checked according to the advanced theory of ore pillar strength. The result showed that the mined - out area can not induce impact ground pressure hazard, but partial caving may occur.
